1.0 Introduction Material model calibration is critical to accurate Discrete Element Method (DEM)-based modeling of granular materials. This article demonstrates an efficient workflow for material model calibration that combines Altair EDEMTM with machine learning through Altair HyperStudy (HST)TM, and Altair romAITM.…
Description The studied device, represented in the figure, is a 4 pair poles induction motor, 3-phases star connected, characterized by: • rated – load power, Pn = 3 kW • rated source voltage, Un= 400 V (line to line value) • rated source frequency, fn = 50 Hz Analysis <!> Working in progress <!> Results <!> Working in…
When it comes to error messages like "Two triangular surfaces overlap" or similar, many users are often at a loss and do not know how to find these surfaces. Unfortunately, the IDs of the mesh elements are currently not available in CADFEKO. They are stored in the .fek file and therefore only visible in POSTFEKO. If the…
Altair Compose team, pleased to announce "Altair Compose" extension for AI Studio, which brings synergy between both the products for ML/AI enthusiasts to perform a wide variety of math operations including linear algebra and matrix manipulations, statistics, differential equations, signal processing, control systems,…
In this video we will discuss the creation of curved members in S-TIMBER. This includes setting up predefined arch profiles, and configuring parameters such as radius, sector angle, and more.
1. Integrating FMI Models into HyperStudy. A new model type to leverage machine learning models standardized with Functional Mock-up Interface. Currently, only scalar type of responses is supported. 2. Leveraging Altair romAI for Predictions Altair romAI (hosted library in Twin Activate and Compose) is now integrated as…
Using morphing tools in HyperMesh you can rapidly change the shape on the FE mesh without severely sacrificing the mesh quality. Shapes can be used for design exploration and optimization. Use the following steps to export shapes from HyperMesh to HyperStudy: 1. From the Morph ribbon, click the Shapes tool 2. Select a…
The model Info note anchored top right exposes default information, some depending of animation mode, that can be customized. There are frequent requests for customizing the Model Info, and this article will propose few use cases that we faced. Where to edit the Model Info note? You can edit Model Info note via the Model…
The material model /MAT/LAW24 (CONC) in Radioss can be used for concrete materials with or without steel reinforcements but also for rocks. The model is robust and is generally a first choice for various cases and applications. Even if it is a complex model, only a minimal set of input parameters is mandatory to run it, as…
Granular materials are everywhere! In fact, they are present in about 70% of all industrial processes. In many cases, the granular material does not exist in isolation - their behavior is significantly influenced by the liquids and gases in which they are found. These particle-fluid, or multi-phase flows, are encountered…
